Abstract: This invention provides a MRI guided ultrasound therapy apparatus. It comprises a static field magnet adapted to apply a static magnetic field in an magnetic resonance volume at a predetermined disposition; at least one ultrasound energy applicator adapted to apply energy within an energy application zone at a predetermined disposition; and The mechanical positioning means for moving said ultrasound energy applicator to position the applicator so that the energy application zone intersects said magnetic resonance volume within said region of the subject. In that apparatus, the static field magnet is open at both ends or open at side. The sided open is upward or downward and the mechanical positioning means of this ultrasound energy applicator is close to and is located outside of this sided open. This invention reduces the space limitation for the mechanical positioning means of the ultrasound transducer. Meanwhile, the non-magnetic requirement on the mechanical positioning means become less greatly and particularly the problem of interference from magnetic field produced by working current of the transducer power cord to MRI system can be solved.

Abstract: The present invention belongs to the technical field of ultrasound therapy, and relates to a swing type high-intensity focused ultrasound therapeutic apparatus and an MRI guided high-intensity focused ultrasound therapeutic system having such a swing type apparatus. The swing type high-intensity focused ultrasound therapeutic apparatus comprises an ultrasound transducer and a moving-locating mechanism thereof, wherein said moving-locating mechanism adopts a swing mechanism which is connected to the ultrasound transducer by a supporting rod. The MRI guided therapeutic system comprises this swing type therapeutic apparatus. In the present invention, the ultrasound transducer moves freely in multiple dimensions and the moving-locating mechanism adopts a swing mechanism, so the interference generated by the MRI guided high-intensity focused ultrasound therapeutic system on the MRI apparatus is quite small and thereby the quality of the ultrasound image obtained is good.
